Some manufacturing companies now use recycled aluminum alloys. It is important that they have the necessary data relating to the control of the machinability of these alloys. Thus. this study on the machinability in the turning of two recycled aluminum alloys by a 6061 R and 6061 R-T6 smelter was conducted. https://www.roneverhart.com/Dudley-ASA-Thunder-ZN-Hycon-12-52-300-Softballs-4A-068Y/
